Adyen Webhook Setup Guide

The Native Webhook URL is generated once an Adyen account has been linked. Each linked account has its own URL.

• Open the linked account in StackOne.
• Open the … menu, select Reconnect and copy the value from Native Webhook URL.
• Close the form without submitting it.
• The URL contains an access token for the linked account. Store it like a secret and paste it only into Adyen.

Sign in to your Adyen Customer Area (use the live Adyen Customer Area for a Production connection).

• Select the company account in the account switcher, so the webhook covers all of its merchant accounts.
• Navigate to Developers > Webhooks.
• Click Create new webhook.

In the Create new webhook dialog, find Standard webhook under Recommended webhooks.

• Click Add next to Standard webhook.

Under General, leave Enabled switched on.

• Enter a Description, for example StackOne
• Leave Merchant accounts set to all merchant accounts, or include only the merchant accounts you want StackOne to receive events for.

Under Server configuration, paste the StackOne Native Webhook URL into URL.

• Set Method to JSON.
• Leave Encryption protocol at TLSv1.3 or TLSv1.2.

Under Security > Authentication method, select No authentication. The Native Webhook URL already identifies and authenticates the linked account.

• An HMAC key is optional; StackOne does not need it to accept the events.

Under Events, click Select all so every event code is sent to StackOne. Only events enabled in StackOne are delivered on to your application.

Click Save configuration.

The new webhook appears on the Webhooks page with the Active status and the description you entered.

Payments webhooks arrive as {"live": "false", "notificationItems": [...]}. JSON deliveries carry one item; StackOne routes every item in the list to its event handler. Token, Management and Platforms webhooks carry a single event with a top-level type.

StackOne answers every delivery with HTTP 200. Adyen retries deliveries that do not get a 2XX response within 10 seconds, so an event can arrive more than once.
